I have purchased a few of the C# and .NET books for Java people,
and this is the best. The feature that stands out for this book
is the great Java to C# class reference, so you can look upa
Java class and find out which C# class does the same thing.

This was truely an amazing book, I've read many .NET books, all of which assume zero knowledge of programming, or very little. So when I skipped the first few chapters, or skipped them (Since I've been a Java Developer for several years), I missed valuable differences between Java and .NET.

Be sure you do know your stuff in Java, or else this book will seem over your head. This is not a beginners book. But if you're a Java developer, or have similar programming experience, this book is 100% for you.

My only quirk with this book, is that at times, it's more of a refrence/comparison, over how to use several key .NET features. And it seemed to jump around a little. So actually I'd probably rate this book a 4.75...but rounding up gives us a 5, which it pretty much deserves.

I highly recomend this book out there for anyone who is NOT a beginner programmer, or comes from a Java background. This book is a MUST read for you.

This book does 3 things:
Firstly, the book presents the spirit and syntax of the C# language. And the presentation is very focused - it's done against a backdrop of Java.
Secondly, the authors do a flyby of the main areas of the .NET Framework Class Libraries. Again, the assumed reader's knowledge of Java motivates the discusion.
Lastly, and most importantly, Java and C# are contrasted rationally. No hype. Just the facts as the authors see them. This is good stuff and useful too.

If you're are an experienced Java developer, you will get a lot from this book. I still recommend to the Java folks that you also read up on the specialty areas, e.g. ADO.NET, Remoting, etc., if you will be working in those areas.

Before I found this book, I was rather lost. I was trying to learn C# and the framework using the docs that came with the .Net Framework installation and was only getting so far. I didn't feel like I was learning it comprehensively.

Even though this book is large, it's easy to read, has example code throughout, and covers a lot of what I needed to know. It had a breadth I found lacking in other Java to .Net books.

Unlike the other books I looked at, this one provides enough information so that you learn how to compile the example code using the free command-line compilers of the .Net Framework SDK rather than making you get Visual Studio.

The author does a good job of describing both the similarities and the differences of the Java 1.4 and .Net, C# languages, API's, without any percievable bias to either. The depth of coverage for both the language, API core's is very good. The depth of coverage for the enterprise topics, e.g., JDBC/ADO, Remoting, web services, XML, etc... is also very good.

This books hits the spot for java developers, the intended audience. A one page description on delegates, for example, has all the information you need to get started with delegates. The Oreilly book has a long winded chapter on it and the essence was lost in the obtuse example provided.

I'm new to C# so I bougtht this book to get started on my project. So far I'm happy with it and feel it's a good starting point for Java programmers who needs to use C#, but there are also drawbacks:

The foremost point is that this book is a little bit old. It's a 2002 book and is talking about .Net 1.0/1.1 and Java 1.3/1.4. Both language have elvoved since then. And this makes the content of the book a little outdated. E.g. the book disencourage the use of C# threadpool since there's no way to control the size of the pool, but this was fixed in .Net 2.0. Also, C#-like features like autoboxing and enum are also added to newer version of Java.

Also I feel there are not enough source code exmaples available in this book.

Overally it's a good book worth reading. Just keep these in mind.

First of all, this is not a book for beginners. There are tons of books out there for beginners and this is not one of them - you must know something about Java.

However if your are an experienced Java programmer, then this is the book for you. I have not read the book to the end but it has been really valuable. It breaks down different parts of the .NET framework and shows how things work.

It should be noted that most people will get by without knowing a lot of the stuff that is covered in this book but for programmers who are interested in the hows and whys in .NET, this book has to be on your shelf.

This is a fantastic book - not only does it cover the syntax of the language, but it also provides great coverage of the class libraries.

If you are a Java developer who wants to learn C#, then this
book is just perfect.

After about 5 years as a java developer, I took a new job as a .NET / C# developer. This book was a great starting point for me. Going from java to c# is a relatively easy transition, but this book makes it much easier and quicker. The book compares the two languages and highlights the differences which made it easier for me to pick up. I'm not a person who reads many books, for work or pleasure, so I don't have much to compare it with. But out of the 10 or so books in my work library, this is the second best book I've used. (The best I own is Effective Java. I'd really like to get one like that for c#.)
